Special Issue Information

Dear Colleagues,

As dam and slope infrastructures endure prolonged service periods, the progressive aging mechanism, manifested as material property degradation and cumulative environmental damage, poses an increasingly severe threat to their structural integrity. Their long-term stability and reliability are increasingly facing various challenges. For example, slope instability and damage to dam foundations may occur due to soil liquefaction, erosion, or overtopping during extreme rainfall or seismic activities, leading to catastrophic consequences such as structural collapse or downstream cascading disasters. Furthermore, changes in hydrological patterns have further exacerbated these risks. Therefore, a reasonable evaluation of slope stability, the implementation of suitable risk-mitigation and reinforcement measures, and the assurance of safe and stable dam operation carry immense engineering significance for hydropower generation, water resource management, and flood control. This Special Issue of the journal will focus on cutting-edge research in disaster mechanisms, risk assessment, and prevention technologies for dam and slope engineering. Topics include, but are not limited to, the following: slope stability analysis under multi-hazard scenarios, failure modes of embankment dams, resilient reinforcement materials, coupled hydro-mechanical modeling, and post-disaster recovery frameworks.

We believe these subjects will be very useful for the further development of dam and slope engineering.

Hydraulic actions may compromise dam foundation stability. Helical anchors have been used in dam foundation reinforcement projects because of the advantages of large uplift and compression bearing capacity, fast installation, and convenient recovery. However, the research on the anchor plate, which plays a key role in the bearing performance of helical anchors, is insufficient at present. Based on the finite element model of helical anchor, this study reveals the failure mode and influencing factors of the anchor plate and establishes the theoretical model of deformation calculation. The results showed that the helical anchor plate had obvious bending deformation when the dam foundation reinforced with a helical anchor reached large deformation. The helical anchor plate can be simplified to a flat circular disk. The stress distribution of the closed flat disk and the open flat disk was consistent with that of the helical disk. The maximum deformation of the closed flat disk was slightly smaller than that of the helical disk (less than 6%), and the deformation of the open flat disk was consistent with that of the helical disk. The results fill the blank of the design basis of helical anchor plate and provide a reference basis for the engineering design. Full article

This study presents a scenario-based, two-dimensional flood modeling approach to assess the potential downstream impacts of a piping-induced dam failure triggered by seismic activity. The case study focuses on the Doğantepe Dam in northwestern Türkiye, located near an active branch of the North Anatolian Fault. Critical deformation zones were previously identified through PLAXIS 2D seismic analyses, which served as the physical basis for a dam break scenario. This scenario was modeled using the HEC-RAS 2D platform, incorporating high-resolution topographic data, reservoir capacity, and spatially varying Manning’s roughness coefficients. The simulation results show that the flood wave reaches downstream settlements within the first 30 min, with water depths exceeding 3.0 m in low-lying areas and flow velocities surpassing 6.0 m/s, reaching up to 7.0 m/s in narrow sections. Inundation extents and hydraulic parameters such as water depth and duration were spatially mapped to assess flood hazards. The study demonstrates that integrating physically based seismic deformation data with hydrodynamic modeling provides a realistic and applicable framework for evaluating flood risks and informing emergency response planning.
